Title: Reducing carbon monoxide content of engine exhaust gases - by adding preheated air side stream to fuel/air mixture
Inventor: WOLTER HERMANN
IPC: F02M23/14
Filed: 1972-03-03
Abstract: The carbon monoxide content of exhaust gases of an i.c. engine is greatly reduced by branching off a side stream of the primary air from the air filter and passing it through the cam shaft housing where it is preheated. This air is admitted to the fuel/air mixture in the suction pipe via a slide valve, controlled by a Bowden wire from the accelerator pedal. CO content during idling may be reduced to 1% and at full load to zero. The appts is simple and can be readily attached to existing petrol engines.

Title: Rotating vane gas compressor for refrigerating plant - has means for injecting the gas in liquid state into the compression chamber
Inventor: MILLER ALLAN SINCLAIR
IPC: F04C29/04
Filed: 1974-08-09
Abstract: The rotary vane compressor receives the gaseous coolant through the inlet channel and pumps this coolant through the outlet channel into a heat exchanger. The gas is liquefied in the heat exchanger and it flows into a liq. tank. The liq. is directed through an expansion valve into another heat exchanger where the liq. is evaporated and the gas is once again passed into the compressor as in a conventional refrigeration compression cycle. A liq. separator is placed between the condenser and the liq. tank from which liq. coolant is tapped through a valve for injecting the liq. into the compression chamber of the compressor. This liq. is evaporated when it meets hot gas within the compressor. The latent heat of the evaporation of the liq. cools the gas during the compression process. The effect of this injection reduces the energy necessary for compressing gas volumes. Maximum temperatures within the compressor are also reduced.
